Erin charged $900 on the current credit card this billing cycle. Erin pays $300 towards the balance by the due date, but is unable to pay the remaining $600. The balance of $600 carries over to the next billing cycle, but he must pay interest on this amount as well. If the APR is 15%, how much interest will be added to the payment for the next billing cycle?

**$690** is the next **bill payment** will be added for the next **billing cycle.**

**What is rate of interest ?**

An** interest rate **tells you how high the cost of borrowing is, or high the rewards are for saving. So, if you're a borrower, the **interest rate** is the amount you are charged for borrowing money, shown as a percentage of the **total amount of the loan**.

Total payment charged = $900

amount paid = $300

amount remained = $600

APR on $600 = 15%

= 600*15/100

= 600*0.15

= **$90**

Therefore, in the next bill **total amount** charged is 600 +90 = **$690**

the change between each line is 105, so we start to add and then you get the resul

The **value **of A in the **number line **is the in-between of 225 and 645 so it is 435.

In **mathematics**, a number line is a **straight **line containing numbers arranged at equal segments or periods throughout its **duration**.

In another word, a **number line **is basically a line in which infinite numbers have been written in ascending order or **increasing **order.

A **horizontal **number line is the most common **representation **and can be extended infinitely in any **direction**.

A, B ≥ 0

**Answer:**

Minimum z =22 at A =6, B=1

See the graph below variable A is on the horizontal axis and variable B on the vertical axis

**Step-by-step explanation:**

We can solve using the graphical method

Min z = 3A + 4B

s.t.

1A + 3B ≥ 9

1A + 1B ≥ 7

A, B ≥ 0

Draw two lines using the constraint equations

The feasible region for the inequality constraints is the region that satisfies all 4 constraints below

1A + 3B ≥ 9

1A + 1B ≥ 7

A, B ≥ 0

This is the heavily shaded region in the graph. The minimum will be at one of the corner points

The function f(x) = (x − 4)(x − 2) is shown. On a coordinate plane, a parabola opens up. It goes through (2, 0), has a vertex at (3, negative 1), and goes through (4, 0). What is the range of the function? all real numbers less than or equal to 3 all real numbers less than or equal to −1 all real numbers greater than or equal to 3 all real numbers greater than or equal to −1 Mark this and return Save and Exit Next

**Step-by-step explanation:**

all real numbers greater than our equal to -1.

as the parabola function is y = something in x², the parabola opens up either up or down.

if the function would have been x = something in y², the parabola would open left or right.

but our parabola here opens therefore up and down.

the vertex is therefore the maximum or minimum of the parabola. y does not get larger or smaller than the y value of the vertex.

as we see that the curve goes through points with y value 0 (which is clearly larger than -1), it means the vertex is a minimum, and the parabola opens up.

therefore the answer at the beginning. any y value of the function can only be greater than or equal to -1.

A rectangular piece of metal is 5 in. longer than it is wide. Squares with sides 1 in. long are cut from the four corners, and the

flaps are folded upward to form an open box. Which equation indicates that the volume of the box is 56 in.³?

The equation which shows the** volume** of **rectangular box** is w² + 5w - 56 = 0.

A** **rectangle is a two-dimensional (**2D**) shape with opposite sides that are parallel as well as equal to each other and four right angles.

The breadth (width) of a rectangle is the shorter side, and the length is the longer side.

The metal's length is 5 inches longer than its width. However, we fold up 1-inch flaps on every side, resulting in a 1-inch box height and an 2-inch decrease in length and width (1 inches on each side). Because the length and width both decrease in the same amount, the length remains 5 inches longer than that of the width.Then, the equations are as follows:

l = w + 5

The height of the box will be 1 inch which is cut and** folded upward.**

vol = l x w x h = 56 in³

Substitute the value of l in the equation.

56 = (w + 5)(w)(1)

56 = w² + 5w

w² + 5w - 56 = 0

Therefore, the **equation** which represent the volume of the **rectangular box** on 56 in.³ is w² + 5w - 56 = 0.

The relationship between two **variables** are **proportional **if their **ratios** are **equivalent** (taken from Khan Academy).

To determine whether or not a relationship is proportional, we can see if two given ratios are the same.

Ross has $2 and $5 notes.

There are 15 more $2-notes than $5-notes.

The total amount of $5-notes is $90 more than the total amount of $2-notes.

What is the total value of all the $5-notes that Ross has?

p.s. get the qn right i will mark u brainliest

By solving a **system of equations **we can conclude that ross has a total of $200 in $5-notes.

Let's define the **variables**:

We know that there are 15 more $2-notes than $5-notes, then:

y = x + 15

And the total amount of $5-notes is $90 more than the total amount of $2-notes.

x*5 = 90 + y*2

Then we have a **system of equations:**

y = x + 15

x*5 = 90 + y*2

Replacing the first equation into the second one we get:

x*5 = 90 + (x + 15)*2

Now we can solve this for x:

x*5 = 90 + x*2 + 30

5*x - x*2 = 90 + 30

3*x = 120

x = 120/3 = 40

x = 40

In this way, we conclude that Ross has 40 of the $5-notes, then the total value is:

40*$5 = $200

The daily cost, in dollars, to produce x Sasquatch Berry Pies is C(x) = 3x + 36, x ≥ 0 and

the price-demand function, in dollars per pie, is p(x) = 12 − 0.5x, 0 ≤ x ≤ 24. Find the price to charge per item in order to maximize profit.

The cost per item for **maximum** profit is $7.50 .

The **maximum** and **minimum value of a function** f(x) is calculated by finding the first and second derivative of f(x).

The cost to produce x pies is given by the cost function

[tex]C(x)=3x+36[/tex]

The price demand function for each pie is given by

[tex]p(x)=12-0.5x[/tex]

Revenue gained from selling x pies

[tex]R(x)=x\times p(x)\\or,R(x)=x\times(12-0.5x)\\or,R(x)=12x-0.5x^2[/tex]

Now profit function is given by

[tex]P(x)=R(x)-C(x)\\or,P(x)=-0.5x^2+12x-3x-36\\or,P(x)=-0.5x^2+9x-36[/tex]

Now we have to find the **maximum** profit. We know that for a function

[tex]P(x)=-0.5x^2+9x-36\\P'(x)=-x+9[/tex]

[tex]P''(x)=-1[/tex]

At P'(x)=0

or,-x+9=0

or, x=9

As P''(x)<0 therefore the profit function P(x) is **maximum** for x at P'(x)=0.

The profit is maximum at x=9

Price to charge per item=12-0.5x

Substituting the value of x we get:

[tex]p(x)=12-(0.5\times 9)\\or,p(x)=12-4.5\\or,p(x)=7.5[/tex]
